What about the market for operating systems? How will that change?

Because of the costs of software and hardware development you'll find two major open source operating systems left in a few years: Red Hat and Novell.

There'll still be hobbyist systems, but for business two is perfect. Any less and you'll have one company dominating to the detriment of the industry, any more and development costs go way up.

Our approach is different to Red Hat's. Red Hat is totally open source, whereas we offer a mixed stack. We do open enterprise software but also have proprietary code that's built to open standards. Our customers don't have heterogeneous software environments either, for that matter.
